Some may be surprised but Bob Carver and his ALS speakers should be added to the list. He's a 3 man operation now. The ALS is perhaps the most sophisticated design that has come about in the past 30+ years of speaker design. Set up correctly, it is perhaps in the top 5 full range designs available.
Notable very small loudspeaker companies (other than Tekton!)
Let's give a shout-out to those very small speaker companies that make excellent products. I'm thinking of true one-man operations (owner-designer-maker) as well as very small ones (owner-designer + a very few employees).
My nominees: Ryan, Prana, Philharmonic, Fritz, Watkins, Vaughn, Chapman, even Daedalus, Salk, Selah.
Who else belongs in this list?
How do they manage to compete with the "big boys", in quality if not in quantity?
